Detailed Description

template<typename ValueType, typename IndexType>
class gko::experimental::factorization::Cholesky< ValueType, IndexType >

Computes a Cholesky factorization of a symmetric, positive-definite sparse matrix. This LinOpFactory returns a Factorization storing the L and L^H factors for the provided system matrix in matrix::Csr format. If no symbolic factorization is provided, it will be computed first. It expects all fill-in entries to be present in the symbolic factorization. If the symbolic factorization is missing some entries, please refer to Ic.

Template Parameters

ValueType	the type used to store values of the system matrix
IndexType	the type used to store sparsity pattern indices of the system matrix
